Note: This step assembly includes the steps, motor, and control unit only. The steps will operate automatically, extending when the RV door opens and retracting when the door closes.

If you want the complete step assembly that also allows you to override the automatic retraction so the steps stay out whether the door is open or closed, you will need a switch kit (sold separately).

The included 4-way plug fits into the existing wiring harness on your RV. Most vehicles should having this wiring already set up. In the event that your RV is missing the wiring, a 4-way pigtail is included to help you hardwire the unit to your RV.

Safety Features

The Kwikee steps include several safety features in an effort to prevent injury to you or your passengers and damage to the RV steps. If an obstruction is detected while extending, the steps will halt and retract back into the stowed position. The steps will also retract when you turn on the vehicles ignition, even if the automatic retraction override has been activated, in case you forget to stow them before driving away.

Will Kwikee Electric Steps Work for You?

Electric steps are typically installed on RVs and some travel trailers. The electric steps from Kwikee install and fold up underneath the camper for simple storage. To ensure you choose the correct size for your application, there are a few measurements you will need to take.

Kwikee In and Out

The Kwikee electric steps attach to the underside of the camper chassis, directly beneath the doorway. To decide which size you'll need, locate the space available underneath your camper that lines up with the doorframe, and measure the width and depth. You will need a mounting space that is at least 30-1/4" wide and 24-11/16" deep.

If it turns out you have more or less space beneath your doorway, there are other step assemblies available with bracket sizes ranging from 24-3/4" wide to 37-1/4" wide. A full list of the available steps is below.

Outriggers for RV Steps

Outriggers - metal brackets that act as an extension (LC301704 - sold separately) - may be needed for installation depending on the model of your original stairs. These provide extra length if the old steps are longer or wider than the new.

Once you know where the mounting bracket will go and what size mounting bracket you need, that spot will be used as the "mounting point" to determine how many steps you will need.

How Many Steps Do You Need?

Kwikee Entry Height

To decide on how many steps you'll need, measure from the mounting point to the ground. This is called the entry height. The entry height should roughly match the height of the steps when they're fully extended, plus 6" to 8" to account for the drop from the bottom step to the ground. This measurement will also tell you how many steps you need.

The chart below displays mounting bracket widths in the first column and entry height measurements in the second column. The third column shows the corresponding part numbers. Use the mounting bracket width and entry height measurements you took to determine which part number will fit your RV. Choose the bracket size that is closest to your measurements without going over.

Replacement Steps, Motor, and Control for Kwikee RV Electric Steps - 42 Series - 25-1/4" Wide - LC372779

Average Customer Rating:  4.2 out of 5 stars   (5 Customer Reviews)

Replaces the electric steps, motor, and control unit for your Kwikee 42 series RV steps. Motor and control unit automatically extend and retract the steps when you open and close your door. Wiring pigtail hardwires to your RV's power.


Was a perfect fit for my 2005 Holiday Rambler Navigator. Listing says 25 1/4” width but it’s really 26 1/4” which is the correct size for Monaco built RV’s. Stainless trim from original steps needs to be transferred. Also I needed to trim some fibreglass panel on the lower fender to free the old steps.


This step was a perfect replacment/upgrade for my coach. The only issue I had is it got damaged during shipment and emailed had to send out another unit. This item should be shipped on a pallet to avoid damage both saving me time and etrailer money. I would order again if the need arose.


As advertised, works well! Thanks

  • Troubleshooting RV Door Steps that Extend and Retract Backwards
    It sounds like you have a couple wires run backwards on your Lippert powered steps. Its hard to say exactly which wires are wrong but most likely a power wire and ground is backwards. The best recommendation I can give would be for you to go over the wiring and verify everything is connected correctly. The green wire gets grounded to the chassis. The white wire gets connected to the power switch which then goes to the positive battery post. The yellow wire gets run to the a keyed power...

  • Kwikee Steps Not Operating After Replacing Trailer Battery
    It sounds like the Kwikee Step part # LC372779 is not getting 12V power from auxiliary battery. The first thing to check is the battery disconnect switch box that is between the positive side of the battery and the 30 amp fuse. If that box is switched to "off" the step will not operate. If the switch is on, I recommend to check the ground wires to the battery to make sure they have a secure connection. The battery should have a secure ground to the chassis.
